The Koronadal City Plaza sits at the heart of Marbel and is where the city gathers for everything from political rallies to Sunday afternoons with ice cream. The plaza is flanked by Saint Alexander's Cathedral and the City Hall building, and the grassy square itself is lined with benches and mature trees that offer some shade from the midday heat.
On weekends the plaza fills with families, vendors selling boiled peanuts and fresh buko, and children chasing pigeons. During the Tinalak Festival in July, the plaza becomes the main stage for cultural performances, with B'laan and T'boli weavers displaying their work and dance groups performing in traditional dress. It is the single spot in Koronadal where the city's indigenous heritage, Spanish Catholic legacy, and Visayan settler culture are all visible at once.
